SPECIFICATION forming part of Letters Patent No. 723,620, dated March24, 1903. pplication filed May 28 1902. Serial No. 108,678. (No model.)

To all whom it may concern: v

Be it known thatl, JOHN PECK, acitizenof the United States, and aresident ofrHaverstraw, in the county of Rockland and State of New York,have inventeda new and Improved Brick-Kiln, of which the following is afull, clear, and exact description.

The object of this invention is to construct a brick-kiln in which thedraft through the arches will be more effective than in the usualconstruction, thus enabling fuel such as oil and soft coal to be usedadvantageously.

This specification is an exact description of one example of myinvention,while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part ofthis specification; in which similar characters ofreference indicatecorresponding parts in all the views Figure 1 is a view showing partofthe-kiln in front elevation and illustratinganother part broken away toshow the interior con-g struction of the arch. Fig. 2 is .a verticalsection on the line 2 2 of Fig. 1, and Fig. 3is a horizontal section ontheline 3 3 of Fig.1.

e indicates the arch, which may be of the usual form and which hasateachend a stoking door-openinge,extendingfrom theground or bottom ofthe-arch upward.

The invention consists in locating in the middle of the arche,intermediate, theend grate-bars a, a sort of grate built up of "brickarranged in checker-work, and according to the construction here shownconsisting of a supporting-pier b, on which are laid the top bricks c,the said top bricks being placed transversely and being spacedfromeachother, so as to allow-the draft to pass freely. between them.The grate-bars a are of metal and'of the, usual construction andextendfrom the checker-work to and into the door openings e. These bars,together with the checker-work formed of the bricks c and b, fill theentire length of the arch.

In burning, the kiln fire is started on the grate-bars a, the firemenstoking simultaneously through. the openings e and the fires at the endsof the arch gradually worked inward toward the center until the twofires meet, and the whole arch will then be under the action of thefire. The advantage of this arrangement is that the bricks Z) and 0 formpractically a grate, and the 'fire' may be burned thereon aseffectively'ason the iron bars a, while at the same time the expense ofmaintainingthe ironbars is avoided, for if iron grate-bars be extendedentirelythrough 'the arch they will soon be burned away at the middleportion of the arch, which is too far from the mouths to be cleaned,because it is extremely difficult, if not impossible, for a workman torake out the ashes from the middle of the arch or slice the. fire, andthe ashes accumulating under and on top of the iron grate at the middleof the arch will cause the bars to be burned away. The brick employed tomake the grate in the middle of the arch are, however, indestructible.building the kiln to fornrthis checker-work in the middle-0f the arch Iemploypreviously-burned brick, since green brick have not the strengthnecessary for thispurpose. By constructing the kiln in this mannerIamenabled to maintain a fire throughout the length of the arch, and Iavoid the necessity of frequently changing the grate-bars.

Having thus described my invention, I

vclaincras new and desire to secure by Letters Patent-I r 1.. Abrick-kiln having a grate at each end of the arch and havinginthefmiddle portion of the arch an open or checker work of brick to whichthe grate-bars extend, for the purpose specified, said brickwork'beingformed of-ra pier running longitudinallyalong the arch, and of topIbricks placed transversely on the pier and extending horizontally fromeach other "to thewalls of the arch, said top brick being spaced fromeach other to admit a circulation of air between them.

checker-Work of brick, outward to and into name to this specification inthe presence of said door-openings at the ends of the arch twosubscribing witnesses. and at an elevation below the tops of saidopenings,wherebyto permit continuous firing JOHN PECK 5 through eachdoor-opening equally upon each Witnesses:

of said iron grates. J. HEFFERNAN,
